Harmony and Kennedy are the first that comes to mind. I guess I can live with Kennedy in a way, I mean she's obnoxious but she kind of has a purpose...
ms. Harmony however - well she was a girl and casting and writers seemed to find her attractive (and for some reason funny, I don't see either) but she was always just a 'filler'. No real point of purpose except to provide the occasional laugh (even if strained). On Angel at the end she mostly seemed to be there to fill the 'girl' quota what with Cordy gone and all... but mostly she was useless there too.
I could definitely have gone 7 years of Buffy and 5 of Angel without ever having seen her... at all.
